Abstract (en)
[origin: DE4426571A1] The invention concerns the use of a stabilizer combination for polyvinylchloride-based moulding compounds. The stabilizer combination contains (a) at least one solid inorganic component in amounts ranging from 0.3 to 3 parts by weight, relative to 100 parts by weight of polyvinylchloride, selected from sodium aluminosilicates, hydrotalcites and calcium-aluminium-hydroxy-phosphites, and (b) at least one solid or liquid zinc salt in amounts corresponding to a zinc to component (a) ratio of from 0.02 to 0.25 to 1, selected from zinc salts of monocarboxylic acids, substituted or unsubstituted benzoic acid and dicarboxylic acids. This stabilizer combination is used in the production of half-hard and soft polyvinylchloride foils by the calendering process in order to prevent a build-up of coating on the rollers used in this process.
